Elliot C. Cook

I'll research this attorney before drafting.

Let me verify the two tracked cases and the IPR/PGR record.

Let me pin down the Microsoft v. InterDigital tracked case.

Elliot C. Cook — Patent Litigation Practice Summary

Specialty / focus areas. Cook is a patent litigator and post-grant practitioner whose casework spans automotive and power electronics (power semiconductors, wireless charging), wireless networking and standards (802.11 Wi-Fi, Bluetooth, 3G/4G SEPs), consumer electronics and network video, mechanical/aerospace (gas turbine engine components), and conference audio/beamforming microphone technology. His prosecution docket leans on high-volume electronics filers (e.g., Toyota, Toshiba, Xiaomi, Alibaba, Mobileye, NEC), and his firm bio lists trade secrets among his practices. The breadth is consistent with Finnegan's electronics-and-mechanical IP litigation profile rather than a single technology silo.

Side preference. His practice is predominantly defense-side for operating companies — he describes experience "both defending against and asserting patent rights," and the representative matters in his firm bio are almost all defenses of manufacturers against NPE/PAE-style suits. The two tracked appearances both list him for plaintiffs, which is a function of procedural posture rather than offensive patent assertion: in both matters his clients (Volkswagen; Microsoft) appear as petitioner/declaratory-side challengers. In substance, the book of business skews toward defending operating companies against patent holders, not prosecuting claims for NPEs.

Firm context. Cook is a partner and Managing Partner of Finnegan, Henderson, Farabow, Garrett & Dunner's Reston, Virginia office; no prior-firm history surfaced in public sources. He is on the faculty of the University of Virginia Law School Trial Advocacy Institute and has co-authored Finnegan's recurring PTAB/Federal Circuit statistics series and the Legal 500 US patent litigation chapter.

Notable cases and outcomes. Documented results include: Intellectual Ventures II LLC v. FedEx, a ~$100M shipping/tracking suit resolved by summary judgment plus a jury verdict of non-infringement (no appeal); Scramoge Technology v. Volkswagen (E.D. Mich.), a four-patent wireless-charging case stayed pending IPR and resolved by dismissal with prejudice and no payment; and the VW/Audi/Bentley/Lamborghini power-electronics defense at the ITC (337-TA-1267) and E.D. Tex., with IPR institutions obtained. He also defended United Technologies in Rolls-Royce v. UTC (swept fan blades, SJ of noninfringement) and Shure in the ClearOne IPR/PGR dispute over beamforming microphone arrays. His tracked Volkswagen matter, Volkswagen Group of America v. Longhorn Automotive Group, includes a PTAB petition that drew a discretionary denial and a failed Federal Circuit mandamus petition (In re Volkswagen Group of America, No. 26-123, nonprecedential order, Mar. 19, 2026) — counsel attribution for that appeal is not confirmed in the sources reviewed. His tracked Microsoft v. InterDigital Patent Holdings matter aligns with Microsoft's challenges to InterDigital's wireless/SEP portfolio, though I could not verify the specific docket from the tracked entry alone.

PTAB / IPR experience. This is a core part of his practice: Finnegan's bio states he has worked on more than 40 IPR matters on both petitioner and patent-owner sides, plus PGRs and ex parte/inter partes reexaminations, and he coordinates the firm's widely cited PTAB disposition and Federal Circuit appeal statistics.

Bar / education (as sourced). Admitted in Virginia, before the USPTO (Reg. No. 61,769), the Federal Circuit, and the D. Colo., E.D. Mich., and E.D. Tex. district courts; J.D., American University Washington College of Law (2008); B.S., Audio Engineering Technology, University of Hartford (2005). Note: Finnegan's current bio says "more than 50" patent litigations while earlier versions said "more than 25" — treat the litigation-count figure as approximate.
